FOO FIGHTERS: We Now Know Who's Injured

Now we know which member of Foo Fighters got injured last week -- Dave Grohl.

Grohl showed up for a discussion at the Pollstar Live conference in Los Angeles Tuesday night with his left arm in a sling. The undisclosed injury happened sometime between the end of the Foos' pre-Super Bowl gig in Atlanta on the 2nd and the 4th, which is when they postponed their pair of New Orleans shows from this Friday and Saturday to May 15th and 6th.

*UPDATE* Dave told the audience that he had planned surgery... on Superbowl Sunday? Strange.
